Messages
The messages described in this section are defined by commands and their parameters defined in the
PDBI.
Connect
After a client has established a socket connection with the PDBA on its well- known port (5873), the
client must issue a Connect request message. The PDBA returns a response message that indicates
whether it is capable of accepting a new connection. There is a limit to the number of PDBI connections;
the default is 16 clients. The connect command defines the Connect message.
If an attempt is made to connect more than the current client limit, a response is returned to the client:
PDBI_TOO_MANY_CONNECTIONS. After the response is returned, the socket is automatically
closed.
Note: Although the default limit is 16 PDBI connections, Tekelec is able to configure and support up
to 128 connections. If more than 16 concurrent client connections are required, contact the Customer
Care Center for more information.
